IMPROVEMENT IN. PROPELLERS.

Specification forming part of Letters Patent No. 12,752, dated April 1'7, 1855.

To all whom it may cori/cern Be it` known that I, WILLIAM D. JONES, of

the city of Poughkeepsie, in the county of` eration of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure l is an elevation or a stern view Fig. 2 is a sectional view,and Fig. 3 is a perspective side v1ew.

A are the disks'or wheels or their equivalents; BB, theshatts or axles; C C, the paddles or buckets; D, the connecting ball-andsocket joint; E, the driving-cogs on disks or wheels; F F, the two driving-pinions; G G, the hinges or their equivalents; H H, the connecting-rings or their equivalents, I denoting the point when the disks or wheels are nearest together and no resistance from the paddles or buckets, and K denoting the point when the disks or wheels are farthest apart and have the greatest power of propulsion.

\ To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

I construct my conical propeller by placing two circular'wheels -A A or disks or their equivalents, with or Without arms, so constructed and set that their axes or shafts B B stand at about one hundred and twenty degrees from' each other, more or less, and

that the peripheries of said disks or Wheels' or vtheir equivalen ts touch each other, or nearly so, at one point, while the faces of said disks `or Wheels A A diverge from each other at 4 about sixty degrees, more or less, in conseat D, or by means of cogs on the edges or on the sides or faces of said disks or wheels at E, matching into each other at the point where the disks or wheels meet, or else by two pinions F F between the said'disks or Wheels gearing into teeth on the faces of said disks or wheels near their edges, or any other suitable means. Onto the faces of these Wheels or disks one or more buckets or paddles C G or their equivalents are attached, standing radially on the face of each of the disks or wheels or their equivalents, and the shape of each of these buckets or paddles C C is such as to occupy and extend to one-half the distance between the said disks or wheels when farthest apart, and, meeting each other, are connected or joined at G in the center, and occupying the whole space between the said disks or wheels or their equivalents, and pairs of these buckets or paddles C C, thus formed, connected, and attached to these 'disks or wheels by radial hinges or joints D D, extending across between the said disks or wheels, are connected at their outer or moving ends byV means of a ring G or suitable joint or its equivalent. The operation of these buckets or paddles as they revolve with and between these inclined wheels or disks is that when any of the buckets or paddles C C have reachedthe point I, where the disks or wheels are nearest together, the said buckets or paddles are closed or folded down fiat, or nearly so,

onto the face of said disks or wheels and pass through the water without offering any resistance; but as said buckets or paddles are moved on by the rotation of the disks or wheels the buckets or paddles C C will evolve and extend, as at K, from the face of the wheels or disks until said pair of buckets or paddles stand at' right angles to the faces of the wheels or disks at the point K, where said disks or wheels are the farthest apart from each other, thereby producing continual andequivalents before detailed. One or more The arrangement and combination of the pairs of paddles or buckets or their equivaparts forming` n propeller, es fully set forth lents may be used between the said disks or in the foregoing speeiieatiomfor the purposes wheels or their equivalents, and one or more above mentioned.

of the propellers thus formed may be applied y to the stern or sides or bottom of the ship or VILLIAM D' JONES vessel in any convenient or suitable manner. Vitnesses:

That I claim as my invention, and desire L. M. NORTHROP,

to secure by Letters Patent, is- S. E. HAIGHT.
